[0002] Release paper is generally used to protect the adhesive. During assembly, the release paper needs to be torn off to expose the adhesive. During the production process, since the release paper is generally made of thin material and has electrostatic adsorption, it is easy to slip during the transfer process of the clamping jaws. As a result, it will be scattered on the surface of the equipment due to untimely adsorption. At the same time, during the tearing process of the release paper, in order to ensure the tearing yield of the release paper, excessive tearing force may cause the bag to be torn and broken. Summary of the Invention

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] In the current automated equipment for tearing off the release paper of bags, the discharge and discarding of the release paper has always been a technical difficulty. Due to the extremely strong electrostatic adsorption of the release paper itself, some release papers will be tightly adsorbed around the clamp after peeling, and the suction mechanism of some release papers will find it difficult to absorb them. As a result, some release papers will be adsorbed around the clamp, causing the next release paper to be scattered on the surface of the equipment during the transfer process, affecting the equipment 5S. If the release paper is scattered to the inside of the next product, it will also affect the equipment yield. At the same time, in the process of tearing off the release paper, in order to ensure the tearing yield of the release paper, excessive tearing force will also cause the bag to be torn and broken. In view of the above situation, a tearing mechanism and a release paper processing mechanism are designed, which can simultaneously improve the tearing yield without damaging the bag and ensure that the torn release paper can be discharged smoothly.

[0049] Taking a packaging bag with release paper attached as an example, the packaging bag includes a main body and an extension section. The main body serves as the loading part, and the product is placed inside. The extension section is provided with adhesive for being bent and attached to the main body.

[0050] Please refer to Figure 1 The release paper handling mechanism 1000 comprises a platform 400, a positioning mechanism 200, and a tearing mechanism 100. The platform 400 is used to place products with release paper attached; the positioning mechanism 200 is used to secure the products; and the tearing mechanism 100 is used to tear the release paper off the products on the platform 400. The packaging bag is placed on the platform 400, and the positioning mechanism 200 is used to secure the packaging bag and ensure stability during the release paper removal process. The tearing mechanism 100 removes the release paper at an angle. The design of the tearing mechanism 100 not only alleviates the problem of release paper slipping, but also mitigates the problem of the release paper being easily damaged during the tearing process.

[0051] Please refer to Figures 2 to 3 The tearing mechanism 100 includes a mounting base 1, a grabbing assembly and a driving device 3. The grabbing assembly includes a grabbing structure 21, and the grabbing structure 21 includes two grabbing parts 211 that can engage with each other. At least one of the two grabbing parts 211 has a stroke that moves toward the other. The two grabbing parts 211 are used to jointly grab the edge of the release paper to be torn off; the driving device 3 is used to drive the grabbing structure 21 to move in an oblique direction to tear off the release paper in the oblique direction.

[0052] In the technical solution of the present invention, the gripping structure 21 is designed not to use a conventional clamping claw structure, but to adopt two mutually engaging gripping parts 211 to pick up the release paper. This meshing form allows the two gripping parts 211 to cooperate more closely with the release paper, ensuring that the release paper does not slip when being torn off. In addition, the driving device 3 drives the gripping structure 21 to move along an oblique direction to tear the release paper, further improving the tearing yield and reducing bag damage.

[0053] Meshing is a state in which two or more things bite or cooperate with each other. The present invention does not limit the specific structural form of the gripping portion 211. The two gripping portions 211 can be meshed with each other. For example, it can be in the form of gear matching. The gripping portion 211 can be a whole gear or a partial gear. In this embodiment, please refer to Figure 3 The end surface of each gripping portion 211 facing the other gripping portion 211 is concave-convex. That is, a stepped groove structure is formed, wherein the end surface corresponding to one gripping portion 211 is provided with multiple convex portions arranged on the same straight line to form a concave-convex structure, and the end surface corresponding to the other gripping portion 211 is provided with multiple concave-convex grooves arranged on the same straight line to form a concave-convex structure, so that the two gripping portions 211 can achieve a meshing effect when they are attached.

[0054] It should be understood that the size of the concave and convex arrangement should be designed with reference to the size of the release paper. Specifically, after the release paper is attached to the adhesive, a portion of it is not in contact with the adhesive, and thus serves as a tearing point, cooperating with the gripping portion 211.

[0055] The two gripping parts 211 may both be movable, and the two can move toward each other or away from each other. The two gripping parts 211 may also be configured such that one is movable and the other is fixed.

[0056] According to the actual production positioning, the two gripping parts 211 can be arranged relative to each other in the horizontal direction or in the up and down directions. For the convenience of placement, in this embodiment, the packaging bag is placed horizontally, and the two gripping parts 211 are arranged relative to each other in the up and down directions. Specifically, the gripping part 211 located above is movably installed in the up and down directions so as to be able to engage with or separate from the gripping part 211 located below. In the initial state, the two gripping parts 211 are separated from each other in the up and down directions, driving the gripping structure 21 to move so that the tearing point of the release paper is placed on the end face of the gripping part 211 located below, driving the gripping part 211 located above to move downward to achieve pressing, thereby completing the gripping action.

[0057] It should be understood that the gripping structure 21 is oblique during the tearing action, and can be horizontal first and then up and down, or can be up and down first and then horizontal when moving and positioning, and there is no limitation here.

[0058] Furthermore, considering the electrostatic properties of release paper, one gripping portion 211 is movable horizontally so as to be offset from the other gripping portion 211. This allows the two gripping portions 211 to be offset after the release paper is removed, preventing the release paper from being trapped between the two gripping portions 211 and repeatedly sticking to them, making it difficult to remove and discard.

[0059] To prevent the release paper from being electrostatically adsorbed on the corresponding gripping portion 211, in some embodiments, the end surfaces of the two gripping portions 211 facing each other are each provided with a first air hole 212. The first air hole 212 is used to connect the air path to blow the release paper away. The first air hole 212 releases air to blow the release paper away, preventing it from adhering to the gripping portion 211. Multiple first air holes 212 can be provided at intervals.

[0060] It should be understood that when the end surface of the gripping portion 211 is concave-convex, the first blowing holes 212 can be correspondingly arranged on multiple concave portions and / or multiple convex portions. Furthermore, the two gripping portions 211 can be separated vertically and staggered horizontally, thereby preventing the first blowing holes 212 from failing to blow the release paper out due to the gripping portions 211 blocking each other during the blowing process, resulting in the release paper not being sucked away.

[0061] Taking production efficiency into consideration, multiple packaging bags are provided for synchronous tearing of the liner. Therefore, multiple gripping structures 21 are provided and are arranged at intervals in the horizontal direction. In one embodiment, the driving device 3 can be provided with multiple driving parts to drive the multiple gripping structures 21 respectively. In this embodiment, the driving device 3 is used to drive the multiple gripping structures 21 to move synchronously.

[0062] It should be noted that the oblique direction mentioned in this application means that it has components in both the horizontal and vertical directions. It can be horizontal first and then upward, or it can be horizontal and vertical synchronously.

[0063] The present invention limits the structural form of the driving device 3, which can be a multi-axis driving device, a robotic arm, etc. The present application sets the driving device 3 as a three-axis driving module, which can move in the three directions of X, Y, and Z, and through coordinated movement, multiple grasping structures 21 can move synchronously in an oblique direction.

[0064] In order to achieve the positioning of the packaging bag, a clamping claw structure or a suction cup structure can be provided to fix the packaging bag on the supporting platform 400. In one embodiment, please refer to Figure 4 and Figure 5The positioning mechanism 200 includes a support portion 210 and a holding portion 220. The support portion 210 is located below the carrier 400 and is movable vertically, contacting the lower surface of the product near the release paper. The holding portion 220 is located above the carrier 400 and is movable vertically, corresponding to the support portion 210, and is used to work together with the support portion 210 to secure the product near the release paper. In this embodiment, the support portion 210 and the holding portion 220 correspond vertically to form a clamping and positioning effect, with the support portion 210 providing the primary support. It should be understood that both the support portion 210 and the holding portion 220 correspond to the extended section of the packaging bag, and their holding positions maintain a certain distance from the release paper, which can be as little as 1 mm. This protects the extended section and mitigates damage to the bag, preventing the release paper from being torn apart by the force of tearing. The tight pressure at this location can counteract the pulling force of the release paper. The extended section of the packaging bag is compressed and loosened by the movement of the supporting portion 210 and the pressing portion 220 , so that the next process or the transfer of the packaging bag is facilitated after the release paper is torn off.

[0065] Since the packaging bag is thin and easily deformed, in order to avoid the packaging bag from being in an uneven state when the support portion 210 and the pressing portion 220 cooperate with each other due to the natural drooping of the packaging bag, which affects the tearing of the film and easily causes wrinkles in the packaging bag, in some embodiments, please refer to Figure 4 The support portion 210 is provided with a second air hole 210a on its surface. The second air hole 210a is used to connect the air path to blow air toward the portion of the product where the release paper is attached. Specifically, in the initial state, at least a portion of the extended section of the packaging bag is suspended. During the upward movement of the support portion 210, air is first blown upward through the second air hole 210a, causing the extended section to transition from a downwardly draped state to a relatively flat state. When the support portion 210 reaches the corresponding position, the air blowing stops, and the extended section naturally falls and is placed horizontally on the end face of the support portion 210. The pressing portion 220 is then controlled to fall and press together. This improves positioning stability and prevents wrinkles in the packaging bag during positioning and pressing.

[0066] Moreover, when multiple packaging bags are torn at the same time, multiple packaging bags need to be positioned accordingly, and the supporting parts 210 are provided in plurality and arranged at intervals in the horizontal direction; the pressing parts 220 are provided in plurality accordingly.

[0067] Based on the above embodiment, each supporting portion 210 should be provided with a second blowing hole 210 a.

[0068] It should be understood that the multiple support parts 210 can be driven to move up and down separately or simultaneously. The positioning mechanism 200 also includes a first mounting plate 230. The first mounting plate 230 is located below the carrier 400 and can move in the up and down direction. The multiple support parts 210 are spaced apart on the first mounting plate 230. The first mounting plate 230 is driven by a linear drive module such as a cylinder and a lead screw.

[0069] Considering the stability of the packaging bag support, a detachable matching block can be set on the side of each supporting part 210. The upper end surface of the matching block is flush with the upper end surface of the supporting part 210, which is used to adjust the support contact area for packaging bags of different sizes.

[0070] It should be understood that the multiple holding portions 220 can be driven up and down individually or simultaneously. The positioning mechanism 200 also includes a second mounting plate 240, which is located above the support platform 400 and can move up and down. The holding portions 220 are elastically mounted on the second mounting plate 240. The second mounting plate 240 is driven by a linear drive module such as a cylinder or a lead screw. The elastic mounting of the holding portions 220 is intended to prevent damage to the packaging bag caused by excessive holding force, providing a safer and more reliable solution.

[0071] It should be noted that the holding portion 220 can be elastically installed by means of a spring or elastic rubber that can be automatically compressed by an external force and automatically rebound after the external force is eliminated. This application does not impose any restrictions on this.

[0072] In addition, when the release paper is removed, the main body of the packaging bag is usually already filled with a product, which may be regular or irregular in shape. Therefore, to prevent movement, the positioning mechanism 200 also includes a pre-pressing portion 250. The pre-pressing portion 250 is fixed to the second mounting plate 240 and spaced apart from the holding portion 220. The pre-pressing portion 250 is used to secure the product to the support platform 400. That is, in this application, the pre-pressing portion 250 and the holding portion 220 are synchronized up and down, making it more compact and reducing the number of parts. Of course, in other embodiments, the pre-pressing portion 250 can also be driven and installed separately, rather than being installed on the second mounting plate 240. It only needs to be spaced apart from the holding portion 220 so that it can correspond to the main body of the packaging bag.

[0073] Furthermore, the lower end surface of the pre-pressing portion 250 is configured to be curved, so as to adapt to the product, thereby adapting to products of different shapes.

[0074] After the release paper is torn off, it may scatter on the device. Therefore, the release paper processing mechanism 1000 also includes a waste suction assembly 300. The waste suction assembly 300 is located to the side of the support platform 400 and corresponds to the gripping structure 21 of the tearing mechanism 100. It is used to collect the torn release paper. The waste suction assembly 300 functions similarly to a vacuum cleaner. After the release paper is separated from the gripping portion 211, it can be sucked into a waste bin for centralized collection.

[0075] When multiple gripping structures 21 are provided, multiple waste suction assemblies 300 are provided accordingly. In this application, multiple waste suction assemblies 300 are arranged along the same straight line at intervals on the sides of the supporting platform 400 and are arranged close to the extension section. The arrangement of multiple waste suction assemblies 300 provides more stable suction.

[0076] In the technical solution of this embodiment, four packaging bags are arranged side by side on the carrier 400, and the extension portion extends from the side end of the carrier 400 or is exposed at the hollow position of the carrier 400. The packaging bags are first positioned by the support portion 210, the holding portion 220 and the pre-pressing portion 250. The holding position of the holding portion 220 is about 2 mm away from the paper mold; then the driving device 3 controls the movement of the grabbing structure 21, and the cylinder controls the grabbing portion 211 to press the paper mold. The release paper is then torn upward at a 45-degree angle along the release paper under the action of the three-axis driving module of the XYZ axis, and the torn release paper is driven to be placed on the waste suction component 300. The waste suction component 300 keeps exhausting air, and the two gripping parts 211 are separated in the upper and lower directions and staggered in the horizontal direction. The first blowing hole 212 is used to prevent the release paper from being electrostatically adhered to the gripping part 211, ensuring that the release paper is sucked away by the waste suction component 300, thereby completing the tearing and waste discharge of the release paper.

[0077] In the technical solution of the present invention, the toothed, concave and convex configuration enables the two gripping portions 211 to mesh with each other. Combined with the air blowing and angled tilting, this not only ensures that the release paper does not slip when being torn off, but also ensures that even if the release paper becomes stuck during waste discharge, it can be blown away smoothly. The angled tearing action further improves the release paper tear-off yield rate. Combined with the positioning of the bag next to the release paper, it eliminates the problem of damage to the bag during tearing, thereby improving the release paper discharge yield rate.

[0078] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
